Mr Dazzle here (aka Col)

The real problem with IE, the need for a multiplicity of internal settings and the reason no-one should use it  is that  IE is just a slightly different version of the windows file browser.

(once upon a time if you opened your file browser and put a web adddress in the search bar you could load the web page)

This means MS have to make it secure as hell because anyone who hacks it can get high level access to your system.

The versions of IE are also not strictly compatible with standard HTML becasue MS throw in weird stuff like active-X controls (which is executable code that can be written into a web page), silverlight compliance and a whole heap of other MS junk

.

Web developers have to write interpretations for all the different  versions of IE and include them in the header of each page.

Also javascript does not play nicely, again, because MS are not standards compliant and eBay are not very good with javasscript themselves.

If you ever have a look through the Windows updates you get regularly you'll find a lot of them are security patches relating to IE.

(MS are patching up newly discovered exploits).

It's the expoits they don't know about are the worry though.

Do yourself a favour and get a different browser; it could save you bitter tears somewhere down the track.
